'Oil tree' in the Bible

And he maketh within the oracle two cherubs, of the oil-tree, ten cubits is their height;

as to the opening of the oracle, he made doors of the oil-tree; the lintel, side-posts, a fifth.

And the two doors are of the oil-tree, and he hath carved upon them carvings of cherubs, and palm-trees, and openings of flowers, and overlaid with gold, and he causeth the gold to go down on the cherubs and on the palm-trees.

And so he hath made for the opening of the temple, side-posts of the oil-tree, from the fourth.
